NEOCYTTUS*, Gilchr. 
Body deep, strongly compressed ; head moderately compressed, the interorbital region 
broad. Mouth moderate; upper jaw with a narrow band of very small pointed teeth; 
sometimes a few similar teeth near the symphysis of the lower jaw and on the vomer. 
5 or 6 branchiostegals. Scales small, imbricated, with spiny edges ; lateral line complete, 
curved anteriorly. Dorsal with VII 31-34 rays, the spines strong; anal with III 29-31 
rays. Caudal truncate. Pectorals short, obtuse, each with 17-21 rays; ventrals each 
with I 6 rays, inserted a little behind the base of pectorals, narrowly separated at the 
base, not folding into a sheath. 
Allied to Oreosoma, C. & V., and Cyttosoma, Gilchrist, which have the ventral fins 
below the pectorals and more widely separated at the base, and have some or all of the 
scales juxtaposed and tubercular. 
82. Neocyttus acanthorhynchus, sp.n. (Plate 28. fig. 3.) 
Back elevated, the profile from head to origin of dorsal fin concave. Depth of body 
14 in the length, length of head 22. Diameter of eye 24, interorbital width 23 in the 
length of head. Maxillary extending a little beyond anterior edge of eye; lower jaw 
as long as eye. Bones of head with spinulose ridges; preeorbital ending in a strong 
antrorse spine, below which are 1 or 2 others directed obliquely downwards; similar 
spines on the preefrontal above the anterior edge of eye. 15 gill-rakers on the lower 
* This genus has recently been established for NV. rhomboidalis, from deep water off the coast of 8. Africa, which 
has smaller scales than VV. acanthorhynchus and no strong spines on the snout.
